Part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
All other embodiments obtained without making creative work shall fall within the protection scope of the present invention.
It please refers to Fig.1, the flow chart of BMC time setting methods that Fig. 1 is provided by the embodiment of the present invention；This method can be with
Including：
Step s100, manual timing initial time is obtained；
Manual timing initial time refers to the timing time of user setting, can be the timing initial time of user setting,
It can be the timing time obtained according to the starting timing time of user setting.At this to the acquisition side of manual timing initial time
Method does not limit, for example will can directly receive the obtained timing initial time of user setting when initial as manual timing
Between；The present timing time can also be obtained in the timing piece timing course of server as manual timing initial time, when
During for the latter, as long as timing piece in the server, which can be realized, can obtain real-time timing time in normal timing course
As manual timing initial time.Manual timing initial time is obtained anyway, during server normal power supply, manually
Timing initial time is identical with the timing time being used in the timing piece of timing in server.
Wherein, the time of manual timing is caused to be lost to prevent server from powering off suddenly, the hand of setting can be directly acquired
The dynamic setting time as manual timing initial time, makes timing piece be carried out at the same time timing with clock chip, can greatly enhance
The stability of timing course.Herein using the manual setting time of the user setting of acquisition as 2018-01-24-09:It is carried out for 34
It introduces, user is inputted by 2018-01-24-09:34 start timing, server receive after by the meter of the time write service device
When component while write clock chip, timing piece and clock chip start simultaneously at timing, after server powers off, timing unit
Time in part loses, and continues timing by clock chip, to keep the continuity of timing course and stability.
In addition, to reduce energy loss to the greatest extent, idle work is reduced, the manual setting time that can receive user setting is backward
Timing piece, which is sent, starts riming instructions；Wherein, enabled instruction includes the write-in information of manual setting time；Then timing is obtained
The timing time of component is as manual timing initial time.Timing piece can be avoided with clock chip in server as possible in this way
Identical timework is carried out at the same time in course of normal operation, reduces the redundancy of timework, reduces unnecessary energy loss.
Herein using the manual setting time of the user setting of acquisition as 2018-01-24-09:Be introduced for 34, user input by
2018-01-24-09:34 start timing, server receive after by the timing piece of the time write service device, in server
The timing time in timing piece is obtained when more idle again, for example is 2018-01-24-09:45, which is written
In clock chip, clock chip is by 2018-01-24-09:45 start timing, timing time and timing piece in clock chip
In timing time it is still identical, after server powers off, clock chip continue timing, with keep the continuity of timing course with
And stability.
Step s200, it is sent to clock chip and starts riming instructions；Wherein, it is initial including manual timing to start riming instructions

I2C realizes the synchronous data transmission of duplex with 1 serial data line (SDA) and 1 serial time clock line (SCL),
Interface line is few, and control mode simplifies, and device packing forms are small, and traffic rate is higher, and the read-write sequence of I2C is relatively more fixed, equipment
Communication follows strictly agreement, therefore I2C buses read-write sequence is relatively fixed more unified, and device drives are write conveniently.Pass through I2C buses
Higher communication speed can be ensured by sending I2C instructions, and the relatively low bit error rate ensures the normal transmission of instruction, avoids timing unit
Part is different from the timing time of clock chip.
Clock chip is installed in BMC mainboards, and concrete model of clock chip is not limited at this, can realize storage
And clocking capability.Timing work( can be achieved in clock chip under server normal power supply and power blackout situation
Energy.Power supply mode of clock chip is not limited at this, can on clock chip integrated power supply device, it is integrated by itself
Supply unit power for it, it is of course also possible to by being connect with the supply unit outside clock chip, by extraneous supply unit
It powers for it, for example electric power support can be provided for clock chip by the button cell of BMC mainboards.
Wherein, due to most of clock chip itself not integrated power supply device, and in the BMC mainboards of server generally
Supply unit is integrated with, to reduce requirement to clock chip, to clock chip by the selection space of bigger, it is preferable that can be with
It is powered by being integrated in BMC for electric installation for clock chip.
Step s300, when after server power-off restarting being manual setting temporal mode, when obtaining the timing of clock chip
Between；
After server powers off, the time of the manual timing in timing piece in server will lose, but clock core
It will continue timing in piece.After Server Restart, judge current time Setting pattern for manual setting temporal mode or NTP moulds
Formula when for manual setting temporal mode, obtains the timing time in clock chip, therefore, the present invention can pass through clock core
The continuous timing of piece ensures the continuity of manual timing in server.
Step s400, timing piece is written into timing time.
The timing time obtained from clock chip is re-write into timing piece, timing piece is counted since the time
When, so as to realize the continuity of server timing.Wherein, timing time is manual according to being inputted when starting for clock chip
The time of timing after timing initial time, such as in 2018-01-24-09:45 get manual timing initial time as 2018-
01-24-10:00, clock chip is according to 2018-01-24-10:00 starts timing, and server power-off restarting after 30 minutes obtains
Timing time should be 2018-01-24-10:30, and it is unrelated with the real time.
Based on above-mentioned technical proposal, BMC time setting methods that the embodiment of the present invention is provided, by obtaining manual timing
Initial time；It is sent to clock chip and starts riming instructions；Wherein, start riming instructions and include writing for manual timing initial time
Enter information, by manual timing initial time write clock chip, clock chip will start timework upon actuation, no matter clothes
Business device is in power up in still power process, and clock chip carries out timing according to the pattern of setting, ensure that service
The continuity of device timing in power process when after server power-off restarting being manual setting temporal mode, obtains clock core
The timing time stored in piece；Timing piece is written into timing time, you can realize the timing time by timing by clock chip
To the transfer of the timing piece of server, it is achieved thereby that by obtaining in manual timing initial time to power-off restarting whole process
The continuity of timing can realize the purpose that still comes into force of time for ensureing manual setting after power-off restarting.
Based on above-described embodiment, after the timing time for obtaining clock chip, the timing situation of clock chip is not done herein
It limits, the timing of clock chip can be stopped after getting timing time and timing piece is written, when can also be always maintained at
The clocking capability of clock chip.Preferably, in order to prevent during the multiple power-off restarting of server timing time loss, Ke Yishe
It puts when server is by network automatic synchronization temporal mode, sends timing halt instruction to clock chip, stop clock core
The timing of piece.When server is manual setting temporal mode, server is it is possible that the feelings of power-off restarting more than once
Condition to prevent the loss of timing time during multiple power-off restarting, can enable clock chip keep manual setting in server
Time status is always maintained at during timing time, in order to the reading of timing time after the multiple power-off restarting of server, when
When detecting startup of server by network automatic synchronization temporal mode (NTP patterns), send timing stopping to clock chip and refer to
It enables, stops the timing of clock chip, the continuity and stability of timing time in timing course can be greatly enhanced.
Based on above-described embodiment, it is preferable that clock chip can pass through itself integrated supply unit and/or BMC mainboards
